The new cartridge was completely identified as the .45-70-405, but was also commonly called the ".45 Government" cartridge in commercial catalogs. The nomenclature of the time was based on several properties of the cartridge:
.45 : nominal bullet diameter, in decimal inches i.e. 0.458 inches (11.4 mm)
70 : wt. of blackpowder charge, in grains i.e. 70 grains (4.5g)
405 : weight of lead bullet, in grains i.e. 405 grains (26.2 g)
